For better bike tires, just add graphene

When it comes to high-end bicycle tires, buyers generally have to choose between light, fast ones and grippier, more durable models. According to Italian tire manufacturer Vittoria, however, that's no longer the case – at least, not with the company's new Graphene Plus rubber.Read More

Beating graphene at its own game

Over the last few years, you'd struggle to have not at least heard mention of an extremely strong, electrically- and thermally-conductive, one-atom thick material called graphene. But now, researchers at the University of Kentucky are looking to create a new material that might just boast even more impressive and useful attributes.Read More

Chance discovery puts graphene electronics closer to mass production

We've heard plenty on the wonderful properties of graphene, but the supermaterial par excellence still hasn't found its way to commercial products because it is too delicate for real-world conditions. Now, in a lucky and perhaps game-changing discovery, scientists at the Brookhaven National Laboratory (BNL) have found that placing graphene on top of common industrial-grade glass is a cheap and effective way of making it resilient and tunable, paving the way for the production of graphene-based electronics on a large scale.Read More

Liquid-like graphene could be the key to understanding black holes

Researchers at Harvard University and Raytheon BBN Technology have discovered that the charged particles inside high-purity graphene behave as a fluid with relativistic properties. This find could lead to devices that efficiently convert heat into electricity, as well as graphene-based chips that can accurately model the behavior of faraway celestial objects like supernovas and black holes.Read More

Graphene successfully interfaced with neurons in the brain

Scientists have long been on a quest to find a way to implant electrodes that interface with neurons into the human brain. If successful, the idea could have huge implications for the treatment of Parkinson's disease and other neurological disorders. Last month, a team of researchers from Italy and the UK made a huge step forward by showing that the world's favorite wonder-material, graphene, can successfully interface with neurons.Read More

Graphene optical lens a billionth of a meter thick breaks the diffraction limit

With the development of photonic chips and nano-optics, the old ground glass lenses can't keep up in the race toward miniaturization. In the search for a suitable replacement, a team from the Swinburne University of Technology has developed a graphene microlens one billionth of a meter thick that can take sharper images of objects the size of a single bacterium and opens the door to improved mobile phones, nanosatellites, and computers.Read More

New catalyst could replace platinum in cheaper fuel cells

A more cost-effective fuel cell catalyst material consisting of iron-nitrogen complexes embedded in tiny islands of graphene could be used in place of costly platinum. Research by teams at Helmholtz Zentrum Berlin and TU Darmstadt have produced the catalyst material and found that its efficiency approaches that of platinum.Read More

Aircraft

A pinch of graphene could keep airplane wings ice-free

Both airplane wings and helicopter rotor blades are subject to one problem – they can both ice up. Although de-icing solutions can be applied when aircraft are on the ground, that doesn't stop ice from eventually forming once they're in the air. That's why scientists at Texas' Rice University have developed a new graphene-based coating that continuously melts ice by conducting an electrical current.Read More
